BARIATRIC Surgery Perth | Best OBESITY and WEIGHT Loss Surgeon - Dr Ravi Rao Gastric bypass roux-en-y surgery


Perth Surgical & Bariatrics offers several options for weight loss surgery. One of the most well-known is Roux-en-Y gastric bypass. Designed to reduce the amount of food you are able to eat by cutting away a part of the stomach, gastric bypass is a permanent procedure that helps patients achieve and maintain weight loss goals.


Gastric Pouch


Stomach Bypassed




Duodenum (bypassed)

When gastric bypass is performed using the “open” approach, an incision is made in the abdomen extending from just below the sternum to an area slightly below the belly button. A stapling device is then used to create a tiny stomach pouch by partitioning the existing stomach, essentially changing its size and preventing too much food to be consumed. The “laparoscopic,” or minimally-invasive, approach follows the same guidelines as the “open surgery,” but is performed internally.

Using five small keyhole-sized incisions, the bariatric surgeon relies on a camera that is inserted into one of the incisions to see inside the body, while using several small instruments inserted through the other incisions to perform the procedure.

Gastric bypass Roux-en-y surgery & many potential benefits.

Patients experience a shorter recovery

Length of stay

  • RNY, SIPS (SADI -S) and other gastric bypass patients only need to stay 1-2 nights in hospital.
  • Most patients recover fully in 2 to 4 weeks.

Benefits of Gastric Bypass or Roux-en-y surgery

Gastric bypass or Roux-en-y surgery offers many potential benefits. Typically, patients experience a shorter recovery and less scarring with laparoscopic surgery than with traditional open surgery. However, it is important to remember that laparoscopic surgery is not appropriate for every patient, and, in some cases, surgeons will not know if they can perform the procedure laparoscopically until the surgery is underway. Various medical conditions may make laparoscopic surgery unsafe for certain patients.

Risks and Considerations

  • Gastric bypass patients may experience dumping syndrome, a very uncomfortable result of consuming high fat and high sugar foods.
  • Gastric bypass is major surgery and carries all the risks of a surgical procedure. Please contact us for more information on these risks.

Possible Complications

  • Cardiovascular problems (especially with unidentified pre-existing heart disease): heart attack, stroke or death
  • Respiratory problems: pneumonia, pulmonary embolus
  • Wound problems: wound infection(<5%), hernia development (1% for laparoscopic)
  • Circulation: problems includes blood clots in legs and blood clots migrating to lungs
  • Stomach/intestinal problems: leak from stomach or intestinal surgical sites requiring additional surgery, intestinal blockage (1-2%), stoma stenosis from scarring (10%), dumping syndrome (cramping bloating, diarrhoea after eating)
  • Nutritional problems: excessive weight loss, vitamin and mineral deficiencies (may need ongoing medications or injections), hair loss, bone weakening, gallstones or kidney stones
  • Injury to nearby organs: spleen requiring splenectomy (<1%), significant liver-bleeding (<1%), or potential for transfusions (<5%)
  • Numerous other less-common complications
  • Death can occur: for laparoscopic gastric bypass (0.5 – 1%)
